  "definition": "1. One of the following:(1) For engines, the date on which the crankshaft is installed in an engine block, with the following exceptions:(i) For engines produced by secondary engine manufacturers under § 1068.262, date of manufacture means the date the engine is received from the original engine manufacturer. You may assign an earlier date up to 30 days before you received the engine, but not before the crankshaft was installed. You may not assign an earlier date if you cannot demonstrate the date the crankshaft was installed.(ii) Manufacturers may assign a date of manufacture at a point in the assembly process later than the date otherwise specified under this definition. For example, a manufacturer may use the build date printed on the label or stamped on the engine as the date of manufacture.(2) For equipment, the date on which the engine is installed, unless otherwise specified in the standard-setting part. Manufacturers may alternatively assign a date of manufacture later in the assembly process.\n\n2. Date on which the certifying vehicle manufacturer completes its manufacturing operations, except as follows:(1) Where the certificate holder is an engine manufacturer that does not manufacture the chassis, the date of manufacture of the vehicle is based on the date assembly of the vehicle is completed.(2) We may approve an alternate date of manufacture based on the date on which the certifying (or primary) manufacturer completes assembly at the place of main assembly, consistent with the provisions of § 1037.601 and 49 CFR 567.4.\n\n3. One of the following with respect to equipment:(1) For outboard engines with under-cowl fuel tanks and for vessels equipped with outboard engines and installed fuel tanks, date of manufacture means the date on which the fuel tank is installed.(2) For all other equipment, date of manufacture has the meaning given in 40 CFR 1068.30.\n\n4. Meaning given in 40 CFR 1068.30. [40 CFR 1054.801 (CFR 2013)][40 CFR 1039.801 (CFR 2013)][40 CFR 1042.901 (CFR 2013)][40 CFR 1045.801 (CFR 2013)]\n\n5. Date on which a manufacturer is issued documentation by FAA (or other competent authority for engines certificated outside the United States) attesting that the given engine conforms to all applicable requirements. This date may not be earlier that the date on which assembly of the engine is complete. Where the manufacturer does not obtain such documentation from FAA (or other competent authority for engines certificated outside the United States), date of manufacture means the date of final assembly of the engine.",
